Description

Technical Field

[0001] This utility model relates to the field of microwave oven technology, and in particular to a fast, high-power microwave oven. Background Technology

[0002] A microwave oven is a kitchen appliance that uses microwaves to heat food. Its core principle is that microwaves generated by a magnetron penetrate food, causing water and fat molecules inside to vibrate at high speed. The friction between the molecules generates heat, achieving uniform heating. Unlike traditional ovens that rely on external heat conduction, it features rapid heating and easy operation. It can be used to heat leftovers, defrost ingredients, and perform simple cooking. Some multi-functional models also support grilling and baking.

[0003] Microwave ovens are highly efficient at heating food. Because microwaves act directly on the polar molecules inside the food, they eliminate the need for heat conduction like traditional cookware. They can quickly heat, defrost, or cook food, saving a lot of time and making them especially suitable for fast-paced lifestyles. Microwaves allow food to be heated evenly inside and out, reducing the chance of some parts being too dry or undercooked. At the same time, short heating times can retain the maximum amount of moisture and some nutrients in the food, avoiding nutrient loss caused by overcooking.

[0004] However, the heating structure is a single tube or non-circular design, resulting in uneven heat distribution, which leads to large local temperature differences in the oven cavity and unbalanced heating of the products; most use fixed-speed motors, and the fixed fan speed is difficult to adapt to different baking needs, resulting in low hot air circulation efficiency and the inability to form a high-intensity directional airflow, resulting in poor and uneven baking effect on the surface of the products; the lack of a dedicated height-enhancing auxiliary structure makes it difficult to optimize the baking space and heating angle, further affecting the effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-4 An embodiment of this utility model is provided: a fast high-power microwave oven, including a body frame 1, an elevated baking tray rack 2 is provided inside the body frame 1, a microwave hot air mechanism 3 is provided on the rear side of the elevated baking tray rack 2, the microwave hot air mechanism 3 is used for rapid heating, an intelligent control mechanism 4 is provided on the top front side of the body frame 1, the intelligent control mechanism 4 is used for multi-level adjustment, and a safety protection mechanism 5 is provided on the rear side of the body frame 1.

[0034] The microwave hot air mechanism 3 includes a centrifugal fan 33. The front side of the centrifugal fan 33 is fixedly connected to the rear side of the raised baking tray 2. Multiple annular heating tubes 31 are fixedly connected to the top and bottom of the raised baking tray 2. A dual magnetron 32 is fixedly connected to the rear side of the inner side of the machine frame 1. A dual high-voltage transformer 34 is fixedly connected to the rear side of the bottom of the inner wall of the machine frame 1. A wave guide assembly 35 is provided on the front side of the top of the inner wall of the machine frame 1. A wave stirring assembly 36 is provided on the rear side of the top of the inner wall of the machine frame 1.

[0035] Specifically, the food to be baked is placed on the raised baking tray 2. The operator inputs a heating command through the intelligent control mechanism 4. After receiving the command, the intelligent control mechanism 4 sends a start signal to the microwave hot air mechanism 3. After the microwave hot air mechanism 3 starts, the dual high-voltage transformer 34 is energized first. The dual high-voltage transformer 34 converts electrical energy into a voltage suitable for the operation of the dual magnetron 32. Through the power conversion of the dual high-voltage transformer 34, a stable operating power is provided to the dual magnetron 32. After obtaining stable power, the dual magnetron 32 generates microwave energy. The microwave energy generated by the dual magnetron 32 is transmitted to the waveguide component 35. The waveguide component 35 guides the microwave energy in a directional manner. At the same time, the wave stirring component 36 is activated and disturbs the microwave energy. Through the directional guidance of the waveguide component 35 and the disturbance of the wave stirring component 36, the microwave energy is evenly distributed in the heating area of ​​the raised baking tray 2, ensuring that all parts of the food can receive microwave energy. Multiple annular heating tubes 31 at the top and bottom of the raised baking rack 2 are energized and generate heat. The heat generated by the annular heating tubes 31 diffuses to the heating area. At the same time, the centrifugal fan 33 starts to rotate, and the rotation of the centrifugal fan 33 forms an airflow. The airflow circulates and transports the heat generated by the annular heating tubes 31 within the heating area. Through the heat generation of the annular heating tubes 31 and the airflow transport by the centrifugal fan 33, uniform heat circulation is achieved within the heating area, so that the surface of the food is quickly grilled. Throughout the heating process, the intelligent control mechanism 4 adjusts the operating status of the dual magnetrons 32, annular heating tubes 31, and centrifugal fan 33 at multiple levels according to the preset program to achieve precise control of the food heating effect. The safety protection mechanism 5 monitors the equipment operating parameters in real time. When the equipment malfunctions, the safety protection mechanism 5 triggers the protection mechanism. Through the monitoring of the safety protection mechanism 5 and the operation regulation of the microwave hot air mechanism 3, the safe and stable operation of the equipment is achieved.

[0036] Reference Figures 2-4 The intelligent control mechanism 4 includes a touch screen 41. The rear of the touch screen 41 is located at the top front of the body frame 1. An electrical component compartment 42 is opened at the top of the body frame 1. A main control board 43 is located inside the rear of the electrical component compartment 42. A relay 44 is located inside the electrical component compartment 42. A cooling air duct assembly 45 is located at the bottom of the body frame 1. An oil fume catalytic deodorization assembly 46 is located at the rear of the body frame 1.

[0037] Specifically, the operator can retrieve preset menus via the touch screen 41. The main control board 43 stores multiple menus, each with multiple preset heating steps. The touch screen 41 transmits the retrieval command to the main control board 43. The main control board 43 sends control signals to the relay 44 according to the menu steps. The relay 44 controls the microwave hot air mechanism 3 to start according to the signal. After the microwave hot air mechanism 3 starts, the main control board 43 adjusts the ten microwave levels of the dual magnetron 32 and the ten hot air levels corresponding to the annular heating tube 31 and centrifugal fan 33 according to the parameters set in the menu. Through the flexible combination of the ten microwave levels and the ten hot air levels, various switching between microwave and hot air heating modes can be achieved, improving the heating effect of the food. At the same time, if the operator needs to customize the heating parameters, the heating steps and levels can be adjusted via the button switch 51. The switch sends a signal to the main control board 43 when the oven door is opened. After receiving the signal, the main control board 43 controls the relay to start the microwave hot air mechanism 3. 44. The operation of the microwave hot air mechanism 3 is cut off to avoid safety risks during operation. During equipment operation, the unique power control system on the main control board 43 is activated to monitor the power consumption of the dual magnetron 32, the ring heating tube 31, and the centrifugal fan 33 in real time. By intelligently adjusting the operating power of each electrical appliance, the total power of the equipment is reduced without affecting the heating effect, adapting to different power usage scenarios. In addition, the cooling air duct component 45 reduces the temperature of the internal components of the machine frame 1 and the electrical component compartment 42 through airflow circulation. The oil fume catalytic deodorization component 46 catalyzes the oil fumes and odors generated by heating. Through the heat dissipation of the cooling air duct component 45 and the purification of the oil fume catalytic deodorization component 46, the stable operation of the equipment and the cleanliness of the environment are ensured. The safety protection mechanism 5 monitors the equipment status in real time. When a problem occurs, the protection mechanism is triggered. Through the monitoring of the safety protection mechanism 5 and the regulation of the main control board 43, the safe operation of the equipment throughout the process is ensured.

[0038] Reference Figures 3-4 The waveguide assembly 35 includes a waveguide cavity 351, the bottom of which is located at the top of the dual magnetron 32. A waveguide cover 352 is fixedly connected to the bottom front side of the waveguide cavity 351. The wave stirring assembly 36 includes a wave stirring element 361, the bottom end of which penetrates the top end of the waveguide cover 352. A wave stirring antenna 362 is fixedly connected to the bottom end of the wave stirring element 361. The cooling air duct assembly 45 includes a cooling fan 451, the bottom end of which is fixedly connected to the front side of the bottom of the body frame 1. An air inlet mesh cover 452 is fixedly connected to the bottom front side of the front side of the body frame 1.

[0039] Specifically, the operator can access the preset menu via the touch screen 41 or customize parameters using the button switch 51. The command is transmitted to the main control board 43 via the touch screen 41. The main control board 43 sends a signal to the relay 44, which controls the microwave hot air mechanism 3 to start. The dual high-voltage transformer 34 is energized to convert electrical energy and provide the appropriate voltage for the dual magnetron 32. The microwave energy generated by the dual magnetron 32 is transmitted to the waveguide cavity 351 located at the bottom and top of the waveguide. The waveguide cavity 351 guides the microwave energy to the waveguide cover 352 fixed at the bottom front. At the same time, the wave stirring component 361 of the wave stirring assembly 36 drives the wave stirring antenna 362 that runs through the top of the waveguide cover 352 to rotate. Through the microwave guidance of the waveguide cavity 351 and the rotation disturbance of the wave stirring antenna 362, the microwave energy is evenly distributed in the heating area of ​​the raised baking tray rack 2. While the microwave is heating, the annular heating tube 31 is energized to generate heat, and the centrifugal fan 33 rotates to form an airflow, circulating the heat in the heating area to achieve rapid heating of the food.

[0040] During equipment operation, the cooling fan 451 of the cooling duct assembly 45 starts, drawing in cool air from the air inlet grille 452 at the bottom front of the unit frame 1. The air inlet grille 452 is magnetically installed and contains a stainless steel mesh. The stainless steel mesh adsorbs oil fumes and dust generated during heating. Through the adsorption of the stainless steel mesh and the filtration of the air inlet grille 452, oil fumes and dust are prevented from entering the electrical component compartment 42 and causing short circuits in the internal electrical components. After the drawn-in cool air circulates inside the unit frame 1 to cool the unit, it is blown out from above the door 542. Driven by the airflow of the cooling fan 451 and the design of the cool air circulation path, the temperature of the unit frame 1 and the electrical component compartment 42 are reduced. The temperature of electrical components is controlled to reduce heat accumulation near the door 542 and prevent overheating of the operating surface. The fume catalytic deodorization component 46 catalyzes the fume and odor generated by heating. The purification by the fume catalytic deodorization component 46 prevents the spread of odor. When the oven door is opened, the switch sends a signal to the main control board 43. The main control board 43 cuts off the operation of the microwave hot air mechanism 3 through the relay 44 to avoid safety risks. The power control system of the main control board 43 adjusts the power of each electrical appliance in real time to adapt to different power usage scenarios. The safety protection mechanism 5 monitors the equipment status in real time and triggers the protection mechanism when a problem occurs. Through the monitoring of the safety protection mechanism 5 and the regulation of the main control board 43, the safe and stable operation of the equipment is ensured.

[0041] Reference Figures 3-5The fume catalytic deodorization component 46 includes an in-furnace fume catalytic device 461, the bottom of which is located on the rear side of the waveguide shroud 352. A flue deodorization device 462 is located on the bottom rear side of the body frame 1. The safety protection mechanism 5 includes a push-button switch 51, which is fixedly connected to the top right end of the front side of the body frame 1. A double door switch 52 is located on the bottom front side of the body frame 1. Rubber feet 53 are fixedly connected to the bottom of the body frame 1 around all four sides. A pull-down furnace door component 54 is located on the front side of the body frame 1. The pull-down furnace door component 54 includes a door hinge 541, the bottom of which is fixedly connected to the front side of the body frame 1. A door body 542 is rotatably connected to the top of the door hinge 541. A handle 543 is fixedly connected to the top front side of the door body 542.

[0042] Specifically, the pull-down oven door assembly 54 adopts a downward-opening design. The operator pulls the door 542 through the handle 543, and the door 542 rotates around the door hinge 541 fixed to the front side of the machine frame 1 to open, making it easy to place food on or remove food from the raised baking tray 2. The operation can effectively prevent burns. The structural design of the pull-down oven door assembly 54 is adapted to the needs of commercial quick access and convenient home use. After the door 542 is closed, the double door switch 52 detects that the door 542 is closed and sends a signal to the main control board 43. The operator can access the menu through the touch screen 41 or set parameters using the button switch 51. The instructions are displayed on the touch screen. 41 transmits to the main control board 43, which sends a signal to the relay 44. The relay 44 controls the microwave hot air mechanism 3 to start, and the dual high-voltage transformer 34 is energized to convert electrical energy to provide the matching voltage for the dual magnetron 32. The microwave energy generated by the dual magnetron 32 is guided by the waveguide cavity 351 to the waveguide cover 352. The wave stirrer 361 drives the wave stirrer antenna 362 to rotate. Through the guidance of the waveguide cavity 351 and the disturbance of the wave stirrer antenna 362, the microwave energy is evenly distributed in the area of ​​the raised baking tray 2. The safety protection mechanism 5 monitors the temperature of the dual magnetron 32 in real time. The annular heating tube 31 is energized to generate heat, and the centrifugal fan 33 rotates to form airflow to circulate heat, so as to achieve rapid heating of food.

[0043] During heating, the fume catalytic device 461 inside the furnace cavity behind the waveguide hood 352 is activated to catalyze the fume generated inside the furnace cavity. Simultaneously, the odor removal device 462 at the bottom rear of the machine frame 1 operates synchronously to further purify the emitted odors, effectively catalyzing and purifying the fume and odor inside the furnace cavity, enabling the equipment to be used in multiple indoor scenarios. The cooling fan 451 of the cooling duct assembly 45 is activated, drawing in cold air from the air inlet mesh 452, circulating inside the machine frame 1, and then blowing it out from above the door 542. Driven by the cooling fan 451 and following the cold air circulation path, the temperature of the machine body and electrical components is reduced, preventing overheating of the operating surface. The rubber feet 53 at the bottom of the machine frame 1 contact the placement surface, providing support and cushioning to ensure stable placement of the equipment. In case of emergency stop... Pressing the button switch 51 on the top right side of the front of the machine frame 1 sends a signal to the main control board 43, which then cuts off the operation of the microwave hot air mechanism 3 via the relay 44. When the door 542 is opened, the double door switch 52 is triggered. Through the detection of the double door switch 52 and the regulation of the main control board 43, the microwave stops working when the door is opened. If the first door switch fails, the second door switch blows the fuse. Through the linkage protection of the double door switch 52, microwave leakage is prevented from causing injury. The power control system of the main control board 43 adjusts the power of each electrical appliance to adapt to different power usage scenarios. The safety protection mechanism 5 monitors the overall status of the equipment in real time and triggers protection when a fault occurs. Through the monitoring of the safety protection mechanism 5 and the regulation of the main control board 43, the safe and stable operation of the equipment is ensured.

[0044] Working principle: The operator first contacts the pull-down oven door assembly 54 and applies pulling force through the handle 543, causing the door 542 to rotate around the door hinge 541 fixed to the front side of the machine frame 1 at the bottom, thus opening the oven door. The downward pull-out design facilitates placing the food to be baked on the raised baking tray 2 and makes it easy to remove the heated food later. It also prevents personnel from being burned by contact with high-temperature areas during operation, meeting the dual needs of quick food handling in commercial scenarios and convenient operation in home scenarios. After the food is placed, the operator closes the door 542. At this time, the double door switch 52 detects that the door 542 is in a closed state and sends a door 542 closing signal to the main control board 43 in the intelligent control mechanism 4, preparing for the equipment to start heating.

[0045] Next, the operator inputs heating commands through the intelligent control mechanism 4. There are two ways to input commands: one is to retrieve preset menus stored in the main control board 43 through the touch screen 41. The main control board 43 stores multiple menus, each with multiple preset heating steps. The touch screen 41 transmits the retrieved commands to the main control board 43. The other is to customize heating parameters through the button switch 51. The button switch 51 transmits the customized commands to the main control board 43. After receiving the commands, the main control board 43 sends control signals to the relay 44. The relay 44 controls the microwave hot air mechanism 3 to start according to the signals, and officially enters the heating stage.

[0046] After the microwave hot air mechanism 3 is started, the dual high-voltage transformer 34 is first energized, converting the externally input electrical energy into a voltage suitable for the operation of the dual magnetron 32. Through the power conversion function of the dual high-voltage transformer 34, a stable working power is provided to the dual magnetron 32. After obtaining stable power, the dual magnetron 32 begins to generate microwave energy, which is transmitted to the waveguide cavity 351 of the waveguide assembly 35. The bottom of the waveguide cavity 351 is located at the top of the dual magnetron 32, which can directionally guide the microwave energy to the waveguide cover 352 fixed at the bottom front. At the same time, the wave stirrer 361 of the wave stirring assembly 36 is activated, which drives the wave stirring antenna 362 that runs through the top of the waveguide cover 352 to rotate. Through the directional guidance of the waveguide cavity 351 and the rotational disturbance of the wave stirring antenna 362, the microwave energy is evenly distributed in the heating area where the raised baking tray 2 is located, ensuring that all parts of the food can receive microwave energy evenly and achieve rapid internal heating of the food.

[0047] Simultaneously with the start of microwave heating, multiple annular heating tubes 31 at the top and bottom of the raised baking tray 2 are powered on at the same time. After being powered on, heat is generated and diffused to the heating area. At this time, the centrifugal fan 33 also starts to rotate. During the rotation, airflow is formed. The airflow circulates and transports the heat generated by the annular heating tubes 31 within the heating area, achieving uniform circulation of heat within the heating area. This allows the surface of the food to quickly form a grilling effect, meeting the heating requirements of crispy outside and tender inside.

[0048] Throughout the heating process, the main control board 43 adjusts the ten microwave settings of the dual magnetron 32 and the ten hot air settings of the annular heating tube 31 and centrifugal fan 33 according to preset menu parameters or custom parameters. Through the flexible combination of the ten microwave settings and the ten hot air settings, various switching between microwave heating and hot air heating modes can be achieved, further improving the heating effect of the food. At the same time, the unique power control system equipped on the main control board 43 is activated, which monitors the power consumption of the dual magnetron 32, annular heating tube 31 and centrifugal fan 33 in real time. Without affecting the heating effect, it intelligently adjusts the operating power of each electrical appliance, reducing the equipment's requirements for the power environment.

[0049] During equipment operation, the cooling fan 451 of the cooling duct assembly 45 starts, drawing in cool air from the air inlet mesh 452 at the bottom front of the unit frame 1. The air inlet mesh 452 is magnetically installed and contains a stainless steel mesh. The stainless steel mesh can absorb oil fumes and dust generated during heating. Through the adsorption of the stainless steel mesh and the filtration of the air inlet mesh 452, oil fumes and dust are prevented from entering the electrical component compartment 42 at the top of the unit frame 1, thus avoiding short circuits in the electrical components inside the compartment 42. The drawn-in cool air circulates inside the unit frame 1, cooling the unit frame 1 and the electrical components inside the compartment 42 before exiting through the door 542. The airflow is blown out from above, and the airflow driven by the cooling fan 451 and the cold air circulation path design effectively reduce the temperature of the machine frame 1 and the temperature of the electrical components inside the electrical component compartment 42. At the same time, it reduces the heat accumulation near the door 542 and avoids the operating surface from overheating and affecting personnel operation. In the fume catalytic deodorization component 46, the fume catalytic device 461 in the furnace cavity behind the waveguide hood 352 is activated to catalyze the fume generated in the furnace cavity. The flue deodorization device 462 at the bottom of the rear side of the machine frame 1 operates simultaneously to further purify the odors discharged by the equipment. It effectively catalyzes and purifies the fume and odors in the furnace cavity without the need for additional exhaust equipment.

[0050] If the dual magnetron 32 overheats, a protection mechanism is immediately triggered to prevent damage to the dual magnetron 32 due to overheating. If the operator opens the door 542 during the heating process, the dual door switch 52 detects the opening of the door 542 and sends a signal to the main control board 43. After receiving the signal, the main control board 43 cuts off the operation of the microwave hot air mechanism 3 through the relay 44 to prevent microwave leakage from causing injury. If one of the dual door switches 52 fails, the other door switch will cause the circuit fuse to blow. Through the linkage protection of the dual door switches 52, the risk of microwave leakage is further eliminated. If an emergency occurs and the equipment needs to be stopped, the operator can press the button switch 51 on the top right side of the front of the machine frame 1. The button switch 51 sends an emergency stop signal to the main control board 43. The main control board 43 quickly cuts off the operation of the microwave hot air mechanism 3 through the relay 44 to ensure the safety of personnel and equipment. In addition, the rubber feet 53 fixed around the bottom of the machine frame 1 contact the placement surface. Through the support and buffering effect of the rubber feet 53, the equipment is placed stably, preventing displacement due to vibration during operation.

[0051] Once the food is heated, the equipment stops operating according to the preset program or operator instructions. The operator then opens the door 542 again via handle 543 and removes the food from the raised baking rack 2.
